As someone who’s spent the last decade guiding trips across the American West and relying on dependable gear, I’ve seen a lot of knives come and go. But the Benchmade 940 Automatic consistently stands out. It’s more than just a blade; it’s a tool that’s earned a place in my pack, and the packs of many professionals I know. This in-depth guide will cover everything you need to know about the Benchmade 940, from its design and variations to its performance in the field, maintenance, and whether it lives up to the hype surrounding its price tag. We’ll also compare it to other popular Benchmade models like the 945 and the Mini Osborne, helping you decide if it’s the best Benchmade knife for your needs.
Understanding the Benchmade 940: Design and Features
The Benchmade 940 is an automatic, one-handed opening knife designed by Mel Pardue, known for his tactical knife designs. It’s built around a robust CPM-S30V stainless steel blade, offering an excellent balance of edge retention, corrosion resistance, and toughness. The automatic opening mechanism, activated by a slide on the spine, is incredibly smooth and reliable – a critical feature when seconds count. But the real magic lies in the ergonomics and materials. The original 940 features aluminum handles, while later iterations, like the Benchmade 940 Titanium and Benchmade 940 Jade, offer lighter weight and a premium feel. The 940 utilizes Benchmade’s AXLE™ locking mechanism, known for its strength and ease of operation.
The Osborne Design Influence
The Benchmade Osborne design, pioneered by Warren Osborne, heavily influences the 940. You’ll notice the signature “kissing” blade geometry, where the blade almost touches the handle when closed, contributing to a slim carry profile. This design philosophy prioritizes a comfortable grip and efficient cutting performance. The 940 takes this design and adds the convenience of automatic deployment. If you're familiar with the Benchmade Osborne 9400, you'll recognize the core design principles.

Benchmade 940 Variants: Finding the Right Fit
The Benchmade 940 variants are numerous, catering to different preferences and budgets. Understanding the differences is crucial when choosing the right model. Here’s a breakdown of some of the most popular options:
- Benchmade 940-1: Original model with aluminum handles and CPM-S30V blade.

Benchmade 940 vs 945: What’s the Difference?
A common question is, “Benchmade 940 vs 945 – which one should I choose?” The 945 is a manual opening knife, meaning it doesn’t have the automatic deployment feature of the 940. It’s generally more affordable and legal in areas where automatic knives are restricted. The 945 also typically features a slightly longer blade. The 940 prioritizes speed and convenience, while the 945 offers simplicity and broader legal compliance.
Benchmade Mini Osborne Review: A Smaller Alternative
For those seeking a more compact option, the Benchmade Mini Osborne review often praises its pocket-friendly size and similar ergonomic benefits to the full-size Osborne/940. While it lacks the automatic opening of the 940, it’s an excellent choice for everyday carry and lighter tasks.
Performance in the Field: A Guide’s Perspective
I’ve used the Benchmade 940 Automatic extensively in various outdoor scenarios, from processing fire-starting materials to preparing food and even emergency gear repair. The automatic opening is a game-changer when you need a blade quickly. The S30V steel holds an edge well enough for most tasks, and the AXLE™ lock provides a secure and confident feel. I’ve found it particularly useful for tasks requiring one-handed operation, like cutting cordage while wearing gloves. The ergonomics are excellent, even with wet or muddy hands.
However, the M4 steel variant, while incredibly sharp, requires more frequent stropping and oiling to prevent rust, especially in humid environments. I’ve also noticed that the automatic mechanism can occasionally accumulate debris, requiring occasional cleaning (more on that later).
Maintenance and Care: Keeping Your Benchmade 940 in Top Condition
Proper maintenance is essential to ensure your Benchmade 940 performs reliably for years to come. Here’s a breakdown of key care steps:
- Cleaning: Regularly clean the blade and mechanism with a soft cloth and a mild solvent. Avoid harsh chemicals.
- Lubrication: Apply a small amount of knife oil to the pivot point, lock face, and automatic mechanism.
- Sharpening: Sharpen the blade as needed using a sharpening stone or a guided sharpening system.
- Automatic Mechanism Care: Periodically disassemble and clean the automatic mechanism to remove debris. Refer to Benchmade’s website for detailed instructions.
- Corrosion Prevention: For M4 steel blades, apply a thin coat of oil after each use and store the knife in a dry environment.

Benchmade Warranty and Customer Support
Benchmade offers a limited lifetime warranty against defects in materials and workmanship. This warranty covers repairs or replacements, but does not cover damage caused by misuse or normal wear and tear. The Benchmade warranty form is readily available on their website. I’ve personally had positive experiences with Benchmade’s customer support, finding them responsive and helpful.
Benchmade 940 Review: Is It Worth the Investment?
The Benchmade 940 Automatic isn’t a cheap knife. However, in my experience, it’s a worthwhile investment for serious outdoor enthusiasts, professionals, and anyone who appreciates quality craftsmanship and reliable performance. The speed and convenience of the automatic opening, combined with the excellent ergonomics and durable construction, make it a standout choice. While the 945 offers a more affordable alternative, the 940’s automatic deployment is a significant advantage in many situations. The Benchmade Taggedout review often highlights its utility for hunters and outdoorsmen.
Before purchasing, consider your local laws regarding automatic knives. Also, think about your specific needs and preferences. If you prioritize lightweight carry, the Titanium version is a great option. If you need maximum edge retention, the M4 steel blade is worth considering, but be prepared for the added maintenance. Ultimately, the Benchmade 940 is a premium knife that delivers on its promises, earning its reputation as one of the best Benchmade knife models available.
